听力原文：W: What are you doing, Bill？ Writing a letter？

M: Yes, and it's not easy.

W: My Aunt Mabel sent me a gift for my birthday. I can't remember which gift was hers, but I want to thank her for it.

M: Oh, that's a difficult problem. When it happens to me, I just write to say" Thank you for the wonderful girl" without saying what a gift was. Are you with me？

W: Yes, thanks. That's a clever idea.

M: When you have a bad memory, you have to be clever.
